All thermal inspections will be performed using the Autel Evo II Enterprise drone using a Flir 640 X 512 thermal imaging sensor with a 13MM lens. We will meet with the client to determine the scope of services, date of installation or age of components to be inspected, type of panels or roofing material and ask for a history of defects.
Infrared Commercial Roof Inspection
Traditional thermal roof scans involved an inspector that that needed roof access and would perform the inspection with a handheld thermal camera using an A-frame ladder to get the proper angle for imaging. By utilizing a drone with a Flir Thermal Imaging Sensor, we are able to acquire the necessary data in a safer and more efficient manner. The thermal roof scan is done shortly after sundown, but we will be on site to take daytime photos prior to the sun setting. While a handheld scan could take several days, most of our inspections can be completed in one night. Any thermal anomalies will be located and evaluated to determine if correction is needed. All roof inspections are performed in accordance with ASTM C1153 roof standards.
Infrared Solar Panel Inspection
Aerial solar panel surveys are faster, more accurate and safer than traditional handheld surveys. Anomalies than can be identified include cell or solar shorts, open loops, offline strings, moisture intrusion, delamination and cracked panels. Another benefit of solar inspections is to perform a survey immediately after installation to get a baseline for future inspections. Solar inspections will be performed midday while the sun is at its highest point. Solar irradiance will be measured at random intervals to ensure that enough thermal contrast is present for accurate reading. All solar panel inspections are performed in accordance with IEC 62446 standards.
Infrared Electrical Infrastructure Inspection
Infrared scans can be used for all overhead electrical infrastructure. For transmission lines it is safer and more cost effective than using a helicopter. For substations it is not only safer and more cost-effective, but the results are instantaneous which leads to quicker repairs, less downtime and increased reliability. Aerial infrared inspections are also a vital tool for regulatory compliance.
2D & 3D Site Mapping
Site mapping can be used for everything from a pre-bid contract to 3D modeling throughout the project. A 2D or orthomosaic map is an overhead map of a survey site or asset. Depending on the size of the project, hundreds or thousands of pictures are taken and stitched together to form a high-resolution map. 2D maps can be used for advertising, site planning or progression of construction projects and for mapping an area for film production or large events.
3D mapping is similar, but the camera angles are different, and it utilizes photogrammetry to provide a 3D map/model of a project. 3D mapping can be used for urban planning and architecture, and it is a more detailed representation of construction site progress monitoring.
Construction Progress Monitoring
Monitoring construction projects can be challenging, but with the aid of a drone, companies can get an aerial view of their jobsite from the planning phases until completion.
Photos and videos taken during these flights can keep everyone informed from the executive or board level down to the project managers or site superintendents. This data not only helps with the progress monitoring, but it also helps with inventory management, volumetric estimation and equipment management.
Inventory management: Being able to view lumber, sheathing and finishing materials on a regular basis can prevent costly delays due to running out of material.
Volumetric Estimation: Project managers can view fill and stone stockpiles to determine if more material is needed, if material can be moved offsite or if an operator can be kept busy transferring material on the jobsite.
Equipment Management: The current status of equipment can be monitored so that idle equipment can be moved to other jobsites if necessary. Rental equipment that is not being used can also be returned earlier which will save money and help keep the project within budget.
Photos and/or videos can be taken on a weekly, bi-weekly or monthly basis. Flights can be planned for early morning, evening or weekends so the crews are not disturbed during working hours. If more detail is required, 3D mapping is also available for the project.
